條件的所有值比較字符串

Question

我想寫一個條件檢查，看看是否$variable是在下面的字符串

$category_id = "348,349,398,399,400,402,404,406,410,415,417,419,421,423,425,434,436,438,439,442,350,444,446,448,450,458,460,461,464,468,470,475,479,480,481,483,485,487,489,491,492,498,499,501,503,506,352,509,511,513,521,523,533,535,538" 

任何幫助深表感謝等於任何價值。

Answer 1

if(in_array($searchValue,explode(",",$category_id))) 
{ 
    // in there 
}
